Paul cited a number of passages from Wikipedia where the omnipotent state uses the analysis of a person's DNA to determine their function in life, a subject covered much more artistically in Aldous Huxley's Brave New World. But Paul is using these passages to scare his listeners into believing that such things are now possible, or soon will be. He wants people to believe that our government is omnipotent and dictatorial, like the one in Gattaca. It's not. Paul is using a fictional example of something that doesn't exist--and never will--to attack our actual government falsely.
Paul, as despicable as his purpose might be, is not plagiarizing because he is reviewing the plot from the movie, Gattaca. Paul says at the beginning of his remarks that all these ideas come from the movie, Gattaca. His use of the plot elements are therefore not plagiarism, but fair use. He never pretends that the ideas are his own.
Maddow showed several passages that Paul had lifted from Wikipedia's description of the movie without giving credit to the source. Wikipedia, however, does not copyright its stories.

Maddow should spend her time criticizing the substance of Rand Paul's speeches, not their style.
